Designer
I worked with an engineer who was technically excellent but dismissed design input in reviews — interrupting, rolling his eyes, calling decisions arbitrary. After two weeks I asked him for a thirty-minute coffee outside the office. I told him plainly that the way reviews were going was making me reluctant to bring early work to him, and that meant he was seeing more late-stage decisions than he should have been. He pushed back at first. I stayed on it and gave two specific examples. He admitted he had been frustrated about a different project entirely. We agreed on a small change: I would walk him through rationale at the start of any review, and he would hold critique until I had finished. Reviews stopped being painful within a month. He was not an easy person, but he was workable once he understood I was not going to absorb the behavior silently. The conversation was uncomfortable for half an hour and saved months of friction.
